going wireless, whats needed?

[unwashed potato!]

wanting to go wireless on my house but dont really know waht is needed.

in my house there is 5 computers all currently on a network sharing the internet and a printer.

What do i need for atleast 2 computers wireless, 2 xboxs, 1 xbox360, and the printer to be wirelessly connected?

Is it possible to keep the current router but attach a wireless connector thing? the router isn't wireless and we dopnt really want to have to buy another

Yes for the computers and Xboxes you just need a wireless access point.

For the printer to be wirelessly connected, that depends - if it's got an ethernet port you'll need a wireless bridge which will allow it to act as a wireless client to connect to your access point.

See here. OcUK also have wireless bridges on the main networking section.
